December 26, 1899, John A. Stone, corn harvester. lThe invention comprises improvements in butt adjusting mechanism as applied to this machine, which will be hereinafter ointed out.

The o ject of my invention is to provide a butt adjusting mechanism having greater eiiiciency in harvesting short corn or feed.

This object is attained by means of the mechanism illustrated by the accompanying drawing, in which- Figure l is a front elevation in perspective of part of a corn harvester having my invention embodied in its construction;

Fig. 2 is a top plan view'of part of the butter mechanism on an enlarged scale;

Fig. 3 is a side elevation of Fig. 2; .and

Fig. i is a detail plan viewof a portion Fig. 5 is atop plan view of a portion of a corn harvester illustrating the butt adjuster and a portionof the binder deck, with `the packer arms and-binding needle thereon.

Referring to the drawings, wherein like reference numerals denote the same parts throughout the several views, 1 represents a passageway forfthe corn leading to a cutting apparatus 2, 3 gathering boards, and 4ithe conveying chains mounted upon the boardsand deriving motion from a traction wheel in substantially the same manner as `described .in-the above noted patent, 5 represents a crank shaft lhaving its lower end journaled in a bearing box 6 secured to the frame `of the machine, and its upper end in a bearing box 7 secured to a vertical frame member 8; the upper endof the crank shaft being connected, by means of a universal coupling 9, with the lowerend of ashaft l0 that derives motion from one ofthe conveying chains d, 11 a binder deck leading toward thebinding mechanism (not shown), and l2 represents a butt adjustingmember disposed vertically relative to said deck, and comprising a forwardly inclined portion 13 having its lower end adjacent the deck 11 and havinga bracket la secured to its front end whereby it is pivotally connected with a bear- ,ing box 15 journaled upon the crank shaft 5, and including an angularly disposed sleeve member 1G received by one end of a controlling bar 17, the opposite end of the bar 'being pivotally connected with one end of an arm 18, having itsopposite end pivotally connected with a fixed part 19.0f the frame of the machine; and 20 represents a yielding stalk engaging finger carried by the front end of the part 13. The part 13 is rigidly secured to a laterally extending member 21, and 22 represents a brace member connecting the two parts. rlrhe upper parts of the members 13 and 2l are turned inward, and 23 represents stalk engaging cleats vertically disposed andsecured to the operative side of the two parts in spaced relation. 24: represents a bearing bracket secured to one end of the part 21, upon its front side, whereby it is pivotally connected with a vertically disposed part 25 at one side of a two-part swinging adjuster supporting rod 26, 27. As shown, the two parts of this rod are lindependently pivoted to a bearing bracket 28 (Fig. d) `fixed to the front of a butter extension 29, the adjacent ends ofthe rods 26 'and 27 being provided with oppositely disposed extensions 30 and 81, journaled in this bearing and positioned `with respect thereto by suitable means, such as cotter pins 32, 83. The opposite end of the rod 27 is provided with a downwardly disposed extension Si pivotally connected, as shown, to the bearing box 7 while the butter extension 29 is disposedin front of the part 2l and is secured toa rearwardly extending arm 35 on the casting 28. 36 represents a hand lever mechanism whereby the butt adjuster may be adjusted in a fore and aft direction as desired. As shown, this mechanism is carried by the frame of the machine and is pivotally connected at 37 with a rearwardlyextending link 38 having on its rear end a laterally disposed extension 39 disposed substantially at right angles to the ,extensions 30 and 31 on the rods 26 and 27,

and likewise j ournaled in the bracket `28 and positioned with respect thereto by any suitable means, such asa cctter pin a0. In Fig.

5 I have illustrated a portionof the binder deck, -With the packer arms and binding needle thereon, the packer rarms 41 being supported and actuated by crank shaft 43, the ends of these arms being provided With the usual links 44 pivoted on a stub shaft 45. The binding needle 42 is supported in the usual manner and has not been illustrated in detail. From an inspection of the construction shown in this figure it Will be clear that the butt adjuster 12 receives the stalks directly fromV the cutting mechanism and squares the butts before they have been acted uponV by the p-acker arms. This is an iinportant feature of my device, since it is practically impossible to square the butts after the packer arms have come into action and have compressed the stalks.

In operation the adjuster moves in an orbital path as controlled by the crank shaft 5 and supporting rods 26 and 27, and the angularly disposed part 13 thereof engages With the sides of the upright stalks immedi ately after they have been cut to move them from the cutting apparatus in an aggressive manner and advances them toward the part 21 in a manner which eectually prevents choking adjacent the cutting apparatus. The part 21 engages the circular cut ends of the stalks to further progressively move the stalks. These tvvo .angularly arranged portions not only prevent choking but also insure the binding of the stalks even When the stalks being handled are very short.

While I have in this disclosure of my invention specifically described `but one form thereof, it is, of course, to Vbe understood that the same is not limited to the form chosen'for purposes of illustration but may be embodied in modified forms Without departing from its spirit.

' What I claim as my invention is :Y

1. In a corn harvester, a frame, cutting mechanism thereon, a crank shaft, a binder deck, a two-part butt adjuster operatively located above said deck in the path` of the corn and adjacent said cutting mechanism, one of said parts engaging the sides of the stalks to move the sameV avvay from the cutting mechanism, the other part engaging'the ends only of the stalks in a further progressive movement, both parts of said butt adjuster being operated from said crank shaft.

2. In a corn harvester, a frame, cutting mechanism thereon, a binder deck, a butt adjuster operatively located above said deck in the path of the corn and adjacent the cut- Y ting mechanism, said butt adjuster including two parts at an angle and rigid With respect to each otherrto act upon the side and end successively of the butt portion of a stalk.

3. vIn a machine of Vthe Yclass described, in combination, a cutting apparatus,'a binder deck, a substantially vertical rotatable'crank shaft located in rearandat one side of said cutting apparatus, and a butt adjuster adjacent said cutting apparatus disposed vertically relative to said binder deck and hav# ing its lovver front end operatively conrearward and laterally therefrom, and the and rigid with the front end, and means for iiected With said crank shaft and inclined lrear end of said butt adjuster inclined from Y controlling the rear end of said vbutt adjuster.

4. In a machine of the class described,'in

combination, a cutting apparatus, a binder deck, a substantially vertical rotatable*craiik shaft `located in rear anda-t one side of said cutting apparatus, and a butt'iadjuster adj acentsaid cutting apparatus disposed vertically relative to said binder deck and operatively .connected with said crank shaft, theV operative portions Vof said adjuster being di` vided into two connectedparts arranged atVY different angles relativeto each other and both operated from said crankshaft. 'f A Y 5. In a machine of the class described, the

combination of Ycutting mechanism, aV crank shaft, a butt adjuster adjacent the cuttingY mechanism operatively connectedto fthe crank shaft and vhaving angularlydisposedv Y VWorking faces, one of which ,acts on the stalks in an upright position andthe other Vof which acts upon the stalks whenthey are prostrate, both parts of said butt adjuster being operated from said crank shaft.

6. In a machine of the class described, the combination of cuttingmechanism, a'crank shaft, a butt adjuster adjacent said cutting mechanism operatively connectedY to the crank shaft, said adjuster having tivo adjacent operative portions for engagement with the stalks at different angles, saidadangularly disposed portions, and

jacent portions being rigid'vvithrespect tov each other, aV brace member connecting the means forV 7.` In a machineiof the class described, the

vcombination of cutting mechanism, and a butt adjuster having angularly disposed Working faces relatively fixed to each other, one formoving the stalks awayy from the progressively moving the stalks by; engaging their ends. j Y j In testimony whereof VIY affix my signature, in the presence of two vvitnessesl l Witnesses :i f J.
